 who are disposed to further the objects of the Academy by 

 original researches, contributions of specimens, or otherwise,

 annual dues of three dollars only. Patrons, and honorary and 

 corresponding members, are exempt from the payment of 

 dues. Each patron and active member not in arrears is 

 entitled to one copy of each publication of the Academy 

 issued after his election.
